Blower Door Test in Vineland, NJ

How Is A Blower Door Test Conducted?

For accurate blower door test in Vineland, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.
